Whether the appeal against the appointed counsel fee was filed within the applicable deadline.
No. The appeal period was ten days, and the filing on 23 March 2016 was manifestly late because the deadline expired on 7 March 2016.
Decisions fixing court-appointed counsel fees are separately appealable under Art. 110 and Art. 319 let. b ch. 1 CPC, and the summary procedure under Art. 119 al. 3 CPC applies, so Art. 321 al. 2 CPC sets a ten-day appeal period.
